Abstract

La présente invention concerne un dispositif magnétique commutable avec un premier et un second aimant permanent (10, 11), ce dispositif étant monté dans un boîtier de sorte que les aimants (10, 11) puissent tourner l'un par rapport à l'autre entre une position complètement fermée dans laquelle les pôles nord et sud de ces aimants sont sensiblement alignés avec, respectivement, les pôles sud et nord du second aimant, ce dispositif présentant alors un champ magnétique externe relativement faible, et une position complètement ouverte dans laquelle les pôles nord et sud du premier aimant sont sensiblement alignés avec, respectivement, les pôles nord et sud du second aimant, ce dispositif présentant alors un champ magnétique externe relativement fort. Des organes (30) de polarisation sont associés de manière opérationnelle à un des aimants (10, 11) ou aux deux aimants, de façon à polariser la rotation relative de ces aimants vers la position complètement ouverte, et le placement de ce dispositif sur un matériau ferromagnétique ou à proximité de ce dernier entraîne la rotation des aimants (10, 11) vers une orientation relative de sorte que ce dispositif présente un champ magnétique externe relativement fort.
